To all whom, it may GOTLCLfT/L.

lie it known that I, BENJ MIN F. DOWNS, a citizen of the United States,residing at Wilof Delaware, have invented'ecrtain new and usefulImprovements in a Combined \Vriting andDrawing Instrument, of which thefollowing is a specification.

My'invention relates to drawing and writing instruments, andhas for itsobject to provide .a combined comp'ass, pen,' and pencil possessingcertain novelcharacteristics that will enable it to be readily convertedfrom impair its us fni'nes's wlien adjusted for any one of such uses.

A further object or my inventionis to provide a constructionwherebywvhenthe device is adapted forn'se as a. drawing-compass the adjusting-armforthe two members and the scribingdeg may be adjustably retained in anyposition by means of a sin le clamping device. I

My invention also embraces certain other minor novel embodiments, aswill be hereinand which are fullyillnstrated in the accompanyingdrawings, in which- Figure 1 is aside view of niyimproved instrument inits-extended form, adaptedfor use as 'a pcnholdcr. Fig. 2 is asimilarview takcn at a right angle to. Fig. 1. Fig. 3 is a side vieivshdwing the instrument in position for use asr drawing-compass. Fig. 4is a detail perspectve vice of the pen and pencil holdingattac-lnirelit, the same being. shown separated. Fig. 5 is a detailperspcetiveviow of one of the membcrsslrowing the'connectinghlnge. is

In the said drawings the body portion of the instrumentis shown formedof two members 1 and 2, united by means of a hinge 3, the latter formedof two semicircular leaves -I, lying in countersunkrecesses in themembers and being soconstrnctod that .no part of said hingewillextcndbcyondthc flush surface of the members 1 and 2".

The member 2 has pivotally united thereto a scribing-leg 5, hereinafterdescribed, a suitsurface of said member.

- as shown in dotted lines.

able sot-screw 6 serving to adjnstably unite the parts. T e member 2 isalso slotted at '7 and split from that point toii's end, for a purposehereinafter to be described.

011 the free end of member 1 is carried the usual compass-point 8, whileintermediate its length said member is recessed longitudinally toreceive the arm 9, pivoted therein at 10 and adapted when retracted tolie flush with the A movable sleeve 11, slotted at one side at 12,serves to partly cover and retain the arm 9 within its recess whendesired. A suitable cap 13, adapted to fit over and conceal thescribing-pin 9, is also adapted to ii t onto the projected end of sleeve11 when in the position shown in Fig. .l and to thus serve as a handlefor mani mlating the instrument.

The scribing-leg 5 is formed hollow and is slot-ted at ii for a portionof its length, and within which is iitted a pen and pencil holder, thesame consisting of two members 15, com

itrally recessed at 16 to receive the lead '17,

and on one of which is provided a countersink 18 for the reception of apen 19, as clearly shown in Fig. 5. A sleeve 20, sliding on thescribing-leg 5, serves, by compressing the slotted end thereof, as ameans for firmly retaining the various parts in an y adj usted position.A sleeve 21, mounted on member 2, serves to cover the hinge 3 when themembers are in, the position shown in Figs. 1 and 2, and thus retainsaid members in alinement.

From the above description the operation of my improved instrument. willbe understood to be as follows: The parts being in the position shown inFig. i, the instrument ready for use as an ordinary pen, except thatsleeve 21 should be located over the hinge 3, New should it be desiredto convert the instrument into a pencil it is only necessary to pushback the sleeve pen and pencil holder, and restore sleeve 20 to itsoriginal position. To convert the instrument into a drawirig-compass,slide sleeves 11 and 21 to the position shown in Fig. 3, the slot 12 inthe former permitting this adjustment, remove cap from over eompasspeint 8 and place on the projected end of sleeve 11, and draw out arm 9from its recess in member 1 and pass it-through the slot 7 of mem- 'ber"3, when by adjusting the member 2 and .20 toward set-screw (5, removeand reverse the scribing-leg 5 to the proper radius and tighteningset-screw I; the instrument is ready for use, as clearly shown in Fig.3.

It will be observed that by reason of the slotting. and splittingiofmember the compression of the pivotojd point of e mnection betweenmemlmr and scribingdeg to retain the latter in any adjusted positionwill also compress and retain the arm U in its slot T, therebyaccomplishing both adjustments by a single means and at a singleoperation Having thus described myinvention, whati claim as new. anddesire to secure by Letters Patent, is

lfihe coml lination of two members hinged together, one member carryingacompass-pin and the other membercarrying a scribing-leg, one of saidmembers being provided with a device adapted to project beyond themeeting end thereof when said members are out of alinement, and a capadapted to tit over the compass-pin when the members are in alinementand to tit over the PIOjGgi'Gd device when the parts are out ofalinement, substantially as set forth.

2 The combination with two members hinged together, one membercarryingacompass-pin and the other member carrying a scribing-leg, of aslotted sliding sleeve on one of said members adapted to project beyond.the meeting end thereof hen said members are out of alinement, and acap adapted to I titover the compass-pin when the members are inalinement and to fit over thcprojoetcd end of said sleeve when themembers are out of alinement, substantially as set forth.

The combination with two members hinged together, one member carrying acompass-pin at its free end and a pivoted arm intermediate its long theothermemberhaving its free end slotted for the reception of said pivotedarm and having pivoted to said free end a scribing leg, of a sel-serewpassing through the slotted end ol.' said member and forming the pivotalconnection between the same and the scribing-leg and adapted tosimnitaneonsly retain the scribingleg and pivoted arm in an adjustedposition, substantially as set forth.

t. In a compass, the eombinatiml with the hinged members thereof, onecarrying a compass-pin and an :uljusting-arm, and the other carrying ascribing-leg pivoted thereto, and adjustable independently of theadjustment of the said members, of a single clamping mechanism adaptedto simultaneously retain said adjusting-arm and scribing-leg in anyadjusted position, substantially as set forth. 5. The combined compass,pen and pent-ii, consisting of two members hinged together, one membercarrying a ctnnpass-pin at its free end, means for retaining-saidmembers in alinement, and means for adjustably rc-- taining them infixed relation to each other when out of alinement, of a hollow slottedscribing-leg pivoted to the other membe'r, a combined pen and pencilholder removably located insaid scribing-leg and. consistiugot twoseparable members centrally recessed to receive a pencil-lead, one ofthe same being provided with a countersink to receive a pen, and asleeve movable on said scril. in;;;-Iog to removably retain said holdertherein, sub stantially as set forth.

In testimon wlnerci'ill have hereunto sol my hand in the presence of twosubscribing witnesses.
